Book excerpt: Excerpt from Annals of Applied Biology, 1933, Vol. 3: The Official Organ of the Association of Economic Biologist IN 1914 complaints were received by the south-eastern Agricultural College at wye of serious diseases affecting the plantations of fig-trees in the district of Sompting, Sussex. On a visit being paid in May 1914 to the affected plantations, fig-trees of all ages were found to be suffering from fungous attacks of two kinds. A species of Botrytis was found on the tips of the branches, apparently gradually killing them back. This disease is still under observation and will be the subject of a further communication. The second disease which occurred was a canker of the branches. In some cases, where old trees were badly attacked, numerous cankers were found, both on the younger branches, and on the old, main branches, often quite close to the ground. With the progress of the disease, the canker area enlarges, until the tissues extending through the branch are killed, with the result that the parts above die. With the successive removal of these cankered branches the productiveness of the tree is soon seriously impaired. The majority of the trees in these plantations are of the variety known as Brown Turkey, but a few are of the White Marseilles variety. It was obvious from the effects produced that this canker disease was of serious economic importance; it was the opinion of the farmer of the largest fig-plantations that unless the cause of the disease could be discovered and a remedy devised the Whole future of Fig - growing in that district was threatened.

Available in PDF, EPUB and Kindle. Book excerpt: In experiments at the Bureau's Salmon-Cultural Laboratory, to determine the excretory products of significance in rearing ponds and the possible effect of these products on fingerling chinook salmon (Oncorhynchus tshawytscha), the results demonstrated that ammonia and urea are the principal products. The relative amounts of these products vary with the concentration of fish and with their metabolic activity. Ammonia assumes dominance in an unfavorable environment. Water temperature, pH, and pond type affect the toxicity of ammonia solutions. Continuous exposure to levels of ammonia normally encountered in rearing ponds produced extensive hyperplasia of the gill epithelium in controlled experiments.
